SPINDLE FOR DOUBLINIG AND SPINNING.

SPECIFICATION forming part of Letters Patent No. 625,039, dated May 16, 1899. Application filed February 16, 1898. Serial No. 670,524. (No model.)

To evil whom it may concern:

Be it known that-I, GEORGE KRAINK, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Spindles for Doubling and Spinning 5 and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The object of my invention is to reduce the strain caused by spinning the thread into yarn and winding it on the bobbin of a spindle, and, furthermore, to perform the act of doubling and spinning at the same time.

In. order to arrive at a more complete understanding of my inventive idea as embodied in the practical means herein shown and described by me, I shall briefly allude to some of the defects in the present system of spinning.

The flier system, by means of the flier, winds the spun yarn on the bobbin by the rotation of the spindle and the flier, and as the I bobbin is loose on the spindle and very light in weight it obtains a velocity in advance of the flier, caused by the momentum of the I bobbin as it is drawn around the axis of the As a consequence the spindle by the yarn. bobbin, as aforesaid, being loose on the spindle, held, in fact, by friction only, causes the yarn to snarl, and as the bobbin increases in fullness with the yarn the weight of the thread increases correspondingly, and proportionately therewith, ofcourse, the diameter of the bobbin, creating a heavier draft on the yarn, whichon fine work is aptto break and cause defects in the yarn. In the ring-andtraveler system as the yarn leaves the drawing-rollers it passes through the guide-wire on the board, said guide-wire situated at some distance above the center of the spindle, and from that enters the traveler, which is loose on the ring, and is then drawn around the ring by the yarn as it is spun. The bobbin,

which is attached to the spindle in this system, draws the traveler around its ring by the yarn as it is spun, and in so doing produces sharp edges, which cut the yarn. The centrifugal force created by the rapid speed with which the traveler is drawn around the ring is also detrimental to the spinning and winding, as it occasions the breaking of the thread, so that where fine yarn is spun and wound it is almost impossible to do so successfully.

In describing my improved spindle I shall call attention to the accompanying drawings, where like letters ofreference indicate corresponding parts'in the different views.

Figure 1 shows a front view of my spindle;

Fig. 2, aside view of the spindle as shown in Fig. 1; Fig. 3, a top view of parts of Fig. 2; Fig. 4, a sectional view of the gearing parts forming part of my improvements, looked at from a front view, as in Fig. 1; Fig. 5, the same parts shown in a side view corresponding to Fig. 2; Fig. 6, a broken top view of the ring and traveler; Fig. 7, a sectional view through a center line m a: in Fig. 6 with the traveler shown in full; Fig. 8, a front view of a modification of the gearing system shown in Fig. 4; Fig. 9, a side view of Fig. 8, and Fig. 10 a broken view of the top of the spindle. In Fig. 1, A indicates the bobbin, mounted on the spindle B by resting on the disk B and revolving with said disk by means of a stud or pin Bi fitting in a corresponding aperture in the adjacent flange A ofnthe bobbin A. The spindle B is supported in the customary manner in the horizontal brackets C and O Secured to the spindle, so as to form a solid part therewith, is a disk D, having a swelling D. Rising perpendicularly from this disk are two slender flier-arms E and E running parallel with the bobbin at a proper distance therefrom, each terminating at the top with a hook, respectively, E on E and F. on Secured around the spindle is a yoke F, consisting of a bush F, fitting around the spindle, and two arms F and F Said arms have each an oblong slot G and G Through these slots pass the hooks E and E so that the yoke has the effect of holding the two flier arms E and E together, the centrifugal force having always heretofore had the effect naturally of spreading them, causing an objectionable amount of friction between the said arms and the ring H. As my invention lays claim to a novel attachment between one of the flier-arms and ring-and-traveler system, I will proceed at this point to describe said ring and traveler. The ring II, which is operated in the customary manner, is fittingly attached to the frame W, to which frame the brackets O and 0 supporting the spindle B, also are attached. Said ring is customarily constructed as seen in the detail view, Fig. 7. The traveler is attached to the ring, as shown in Fig. 7, and is also of the usual construction, fittingly secured to the collar J and having eye J, through which the yarn passes previous to its being wound on the bobbin; but, in addition, I have furnished a hook or eye I, which is secured around the flier-arm E, thus establishing a connection between the traveler I and the flier, resulting naturally in a united revolving motion of both these elements simultaneously. This improvement is allied to the reconstruction of my spindle, whichreconstruction I shall proceed to explain. As I stated in my preamble, the bobbin when loose on the spindle obtains an increased velocity over the flier; but even when attached according to the flier system to the spindle-disk D by appropriate means for'instance, as shown in Fig. 4, by a pin B fitting in a corresponding hole in the bobbin a certain disproportion in the winding of the yarn on the bobbin, even though the flier and the bobbin in this instance have the same speed, will, as before stated, cause damage to the spinning. To obviate this evil, I have introduced a system of gearing relative to the bobbin so proportioned that as the yarn is spun and wound on the bobbin and the diameter consequently grows no increased strain will be incurred and the yarn will be wound evenly on the bobbin,avoiding the formation of sharp edges. Referringto the enlarged detail views in Figs. 4 and 5 showing this gearing, K indicates an internally-screw-cut bush resting in and securely attached to a recess formed in the upper part K of the bracket 0 and consequently stationary. Gearing into this internally-screw-cut bush is a pinion L, pivoted in the spindle B itself by a pin L and lying in a recess cut out for such purpose. This pinion gears into a companion pinion L pivoted in the spindle on a pin L which has mounted on one end of it one of a pair of miter-gears M, whose companion gear M is attached firmly to a bush M lying loose around the spindle, which bush finally has the disk Bfastened firmly toit, on which the flange A of the bobbin A rests and is held by the pin B The operative method of the spindle. will thus be seen to be the following: When a strap or belt is applied to the pulley N, affixed to the spindle in the usual manner, the spindle B, having the disk D. with the flierarms attached and yoke F securing the said flier-arms together, and the traveler I will revolve as one unitary element and with the speed received direct through the medium of the belt. The bobbin, on the contrary, will be revolved slower and at any desired speed, regulated entirely by the proportion given to the respective gearing-wheels by its being secured to the disk B, to which disk is attached the miter-gear M, gearing into the mitergear M, mounted on the pin L which supports pinion L meshing with its companion pinion L, which finally, by the revolving motion of the spindle, is driven by the internal worm-gear thread in the bush K. The modification of this gearing, as illustrated in Figs. 8 and 9, consistsin abolishing the miter-gears and furnishing the disk B, on which bobbin rests, on its under side with teeth 0, said teeth gearing into a pinion P, mounted on the pin L said pin having, as before, the pinion L supported thereon, L gearing into an intermediate pinion Q instead of directlyinto pinion L, and the pinion L, as before, being revolved by being in gearing contact with the stationary internal gearing in the bush K. When the combined threads or yarn are then introduced from their respective rollers to be wound on the bobbin A, it is ac= complished in the following manner: The up per end of the spindle B- (see Fig. 10) is bored out hollow from the end and down to the hole Down through this channel B the yarn B 13 passes, as shown in Fig. 1, and out through the hole B down to one of the slots F or F in the yoke F and from thence through the the traveler I onto the bobbin A.

The special inventive features in this my improved spindle will thus be seen to con sist, first, in the gearing means introduced whereby the bobbin is driven independently of the spindle; secondly, thelocking together of the fiier arms; thirdly, the connection established between the traveler and the flier. arm, and, finally, in the hollow construction of the end of the spindle permitting the introduction of the yarn at that point, all of which innovations I shall now proceed to set forth in the hereunto attached claims, for which I pray protection by Letters Patent.

I claim 1. The combination with a doubling and spinning spindle of the flier, the ring and traveler, brackets supporting the spindle, a yoke having its collar embracing the spindle and each of its arms terminating with a slot embracing its respective flier-arm, the upper ends of the flier-arms being curved for the purposes set forth substantially as described.

2. In a spindle mechanism the combination of the spindle and the flier, brackets sup,-

porting the spindle, a loose disk adapted to revolve around the spindle and to have the bobbin mounted thereon,an internally-screwcut bush inserted in one of the said bracketarms supporting the spindle, gearing means intermediate the said screw-cut bush and disk and driven by the bush substantially as described.

3. In a spindle mechanism the combination of the spindle, brackets supporting the spin ICC of the spindle mounted in supportiilg-brackets, the flier, the ring and traveler, spur-pinions pivoted in spaces cut in the spindle for such purpose, the bobbin embracing the spindle loosely and mounted on a disk having gearing means attached, an internal Wormgear immovably fixed in one of the spindlesupporting brackets, gearing means connecting said internal Wormgear and disk, the spindle having a passage-Way lying longitudinally of its axis terminating at an appropriate distance from the top of the spindle and through an opening in the side of the spindle, yoke-arms receiving the yarn after its passage through said passage-Way and. a trave1er-eye leading the yarn onto the bobbin for the purposes specified substantially as it is described.

5, The combination in a doubling and spin ning spindle of the spindle, a loose disk adapted to revolve around the spindle to have the bobbin mounted thereon, spindle-supporting brackets, a screw-cut bush inserted in one of said brackets, gearing means intermediate the said screw-cut bush and the disk having the bobbin mounted thereon, the traveler furnished-With means attaching it to one of the flier-arms for the purposes set forth substan= tially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 12th day of January, A. D. 1898.

GEORGE KRAINK.
